The "How I Met Your Mother" star will direct and appear alongside the "Martha Marcy May Marlene" actress.

Two rising stars of the independent film scene are getting together for a movie project.

Josh Radnor, the How I Met Your Mother star who made his directorial debut with the 2010 Sundance hit HappyThankYouMorePlease, is getting behind the camera again for an indie love story that he will star in with Elizabeth Olsen, who made a splash at Sundance this year with Martha Marcy May Marlene.

Radnor will direct Liberal Arts from script he wrote, prepping a shoot this spring, while he is on hiatus from his hit show, which is now in its sixth season.

Tom Sawyer Entertainment, which was behind HappyThankYouMorePlease, and BCDF Pictures are producing. BCDF is also financing.

The film centers on a 35 year-old (Radnor), still yearning for the life of a college student, who must come to terms with his age and responsibilities.

Olsen plays a 19-year-old college student who falls for Radnor’s character over a shared love of music and literature. She wants to make it work with the man but her immaturity makes it impossible for her to see the obvious obstacles.

Martha Marcy May Marlene opened the eyes of Hollywood to Olsen, until then best known as the younger sister of twin thesps Ashley and Mary-Kate Olsen. Propelled by strong buzz, the movie was one of the hot titles at Sundance and secured a distribution deal with Fox Searchlight.

Olsen is currently in Barcelona shooting Red Lights opposite Robert De Niro, Sigourney Weaver and Cillian Murphy.
